HARROW AN D ROLLER.

SPECIFICATION forming part of Letters Patent No. 396,068, dated January 15, 1889.

Application filed September 17, 1888. Serial No. 285,655. (No model.)

To all whom. t may concern:

Be it known that I, .TEssE BOLLINGER, a citizen of the United States, residing at Carrollton, in the county of Carroll and State of Maryland, have invented certain new and useful Improvements in a Combined l'larrow and Roller; and I do hereby declare the following to be a full, clear, and exact desc-ription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in a combined harrow and roller; and it consists in the novel construction and arrangement of parts, all as will be hereinafter fully described,

and more particularly pointed out in the. ap-` pended claims.

The annexed drawings, to which reference is made, fully illustrate my invention, in which- Figure l represents a perspective view of my'deviee. Fig. l is a vertical longitudinal sectional view of the same. Fig. 3 is a detail view of the tube k. Fig. 4 is a detail view of the front harrow.

Referring by letter to the annexed drawings, A designates the harrow-frame, consisting of the parallel side bars, a, which are curved on their edges and are connected together by cross-bars l), c, and d. Between the side bars are arranged the' revolving toothbars e, which are journaled at their ends to said side bars, as shown at f'. These bars c are provided with harrow-teeth g, that are securely fastened thereto. Secured to these toothed bars e and arising therefrom are rods 71, which are pivoted at their end to the horizontal bars 'i fi, which latter are connected, front and rear, by a cross-bar, j j, thus forming a pivoted frame above the harrow-teeth. Connected to the front cross-bar of this frame is a forked arm, 7o, which is connected by its outer end to a lever, Z, having a series of perforations, m, thereby affording adjustment of said forked arm in order to give the teeth any desired angle, as will be further eX- plained. This lever Z is made fast at its lower end to the middle cross-bar of the frame A.

To the upper end of the lever Z is attached one end of a cord or wire, n, while the opposite end thereof is connected to a shaft, 0, loetween two small rollers, pp, which revolve tol pivoted platform, u, which is operated by the drivers foot in adjusting the harrow.

In rear of the harrow I provide a landroller, ll, which is journaled at its ends to a curved bar, fr, on each side of the frame A. These bars are pivoted or fulcrumed at w to a short standard, fc, on the rear cross-bar of the harrow-frame. The forward end of this lever or bar fv is slotted, as at y, through which passes a pin, e, that connects the short arm a of the angular lever b with said slotted bar i. This angular arm b is pivoted at c to the side bar of the harrow-frame, while the long arm d extends upwardly and the two arms d d are connected to one another by a cross-rod, e', thatserves as a handle for operating the angular arms aforesaid.

The drivers seat f is bolted to two parallel inclined bars, g g. The forward ends thereof are secured to the middle cross-bar of the harrow-frame, and the same are secured to and are supported on the standards on the rear cross-bar of said harrow-frame, as shown in the drawings.4

C indicates a curved lever, the forward end of which is hinged at 7L to the middle crossbar of the frame A, and the same is provided with notches t', either of which is designed to en gage the rear cross bar or rod of the pivoted frame. .This lever Cpasses through a slot, j

in a tubular standard, k, leaving an extended end, l', in front of the drivers seat. Passing transversely through this lever is a pin, m', that has its vertical play in slots a made in the sides of said tube, and within this tube is arranged a coiled spring, o', which extends upwardly against the lower edge of the notched lever aforesaid, and said tubular standard is pivoted at its lower end to plates secured to the front cross-piece of the foot-treadle or frame above the hind roller. has a hand-lever, p', the forward end of which is rigidly attached to said frame.

On the under side of the foot-treadle or pivoted frame I provide springs q', which are secured by one end to the harrow-frame, while the free outer ends bear upwardly against This frame alsol A IOO the under side of the l'oot-plattornn as at r', thereby keepingI the small rollers t'rom engagement with the laml-roller when the machine is in operation.

On the sides of the llarrow-tramel provide bars s', which are perforated to receive a pin, t', which is designed to hold the short arm as well as the entire angular lever in a desired position.

D represents a lainl-roller,\\'l1,iehV is arranged in tro'nt ot' the barrow, and the same is journaled to an iron t'rame secured to the dratttongue, as shown in the drawings.

The rear end ot' the draft-tongue is provided with a clevis, n', which is connected to the barrow-trame by a hook, fu', eiitering the eye w on said clevis, thus providinga swivelconnection betwveen t-he draft-tongue and harrow.

E designates a single barrow-bar having` the teeth af', and the same is hinged at y to the iron frame ol the draft-tongue. This bar is provided about its center with a loopfiron, 2', which spans the tongue, and connected to the same is a coiled spring, a2, that is by its other end connected to a bolt on the rear end ot' said tongue. A catch-hook, b2, on the tongue serves to hold the barrow-teeth not only in a vertical, position, but to hold them oit' the ground when it is desired.

Having thus fully described the several parts of which my device is composed, l will now proceed to describe its operation.

It will be observed from the above description and by reference to the annexed drawings that when the harrow-teeth are in their normal position for harrowing the ground the pivoted frame above the teeth is held firmly in place by the notch in the curved lever, thereby resisting' the strain t'rom the teeth, and when it is desired to relieve said teeth from rubbish collect ed thereon the driver presses upon the extended end of said lever, which causes the notch to disengag'etrom the rear cross-rod ot' the pivoted trame. The same can also be accomplished by raising the hand-lever on the Foot-treadle or plattform. These movements will then cause the teeth to partially revolve and assume nearly a. horizontal position, thus allowingI what rubbish that had accumulated to pass out to the rear of the machine, after which, in ordertoeause the teeth of the harrow to assume their normal position ior harrowing, the driver presses upon the pivoted platform, thus causing the small rollers to engage the land-roller at the same time the horses are moving lforward, and by such engagement said rollers are caused to turn, thereby winding` upon its axle or shat't the cord, which latter draws rearwardly the upper end ot' the vertical bar, and by means ot' the forked arm throws the pivoted frame rearwardly, thus causingthe teeth to assume their tirst position. This moven nientis continued until the 'rear bar ot' the trame drops in the notch on the lever. The driver then .releases the toot-plaftf'orm, an d the springs beneath ititsnce, it to rise, thus disengaging' the small rollers from the landroller, and when it is desired to `give the teeth ot the harrow a forward pitch theeross-bar in the frame is caused to engag'ethe other notch iu the lever aforesaid.

The hand-lever (jonnecting' the two angular levers together is 'used 'for the purpose olf raising' the rear roller or lt'uveringl it. ly forcing1 said lever rearwardly the roller is pressed onto the ground and causes the harrow to rise and clear the same, and by t'oreing the lever forward teeth are caused to enter the ground at different depths. This operation is caused through the medium ot the curved bars and angular leversbars, and the latter is held in dii't'erent positions by the pin passing` through the perforated bar on the side bars ot' the harrow-tranie and in t'ront ol the shortarm et' the angular lever.

The front roller is arranged to admit ot it.` turning in a small space, and the :front har row is held in a vertical position by the coiled spring, which gives when there is rubbish aeeumulated, and allows the harrow to dump, and when relieved of the load the springI causes it to assume its normal position.

The hook on the tongue can be set by its end notch to hold the trout harrow tirml y, it desired, and the said harrow can be held in a position almost horizontal by placing the other notch in engagement with the loop spanningI the tongue.

'1. ln a combined landro|ler and hai-row, the combination, with the pivoted harrowbars, ot' the pivoted trame secured thereto, the curved lever havingl the notches, the tubular standard provided with the eoiled spring, angular lever, slotted curved pivoted side bars t'or the rear roller, the tilting.;l trame provided with the small rollers and the cord, and the vertical lever connected to said cord and to the l'iivoted t "une and harrow-trame, substantially as described.

The ctnnbination, wit-h theharrow-trame provided with the teeth and the operating' parts conneetml thereto, as described, ot' the trontharrow hinged to the 'iframe of the tongue and provided with the loop-bar, coil-spring, and retaining-hook pivoted to said tongue, substantially as tflescribed.

In testimony whereof.' l altix mysignatu re in presence ol' two witnesses.
